Materials Testing Services Rockdale County Judicial and Administrative Complex - Phase 1 Dear Mr. Gonzalez: Please find attached our additional funds request to replenish specific line items under the existing PO #122918 for Construction Materials Testing services at the Rockdale County - Judicial and Admin Complex Phase 1. We have reviewed our previous invoices to capture the total money spent on out-of- scope work that was requested by the design/construction team. The totals for nsuitable soil material quantification and haul-off documentation, environmenta. soil sampling for semi-volatiles and additional PM time accounted for $21,770, as noted on the attached sheets. These services were not included in our initial proposal and have contributed to our funds request. We have provided additional supporting documentation via a budget analysis that depicts the actual time spent VS. our initial proposal to highlight how the testing funds have been consumed to date. Based on our discussions with the construction team, we understand that the majority oft the earthwork activities are close to complete, and that the grading contractor is expected to demobilize at the end of this week. Moving forward, our inspections should be periodic and scheduled on a daily/regular basis by McCarthy/Bamsley to ensure that the Schedule of Special Inspections items are being met. Based on the current stage of construction, we believe that funds on the order of $51,360 should be availed to replenish specific line items in the existing purchase order. We also advise adding a contingency of 10% or $17,041 for a total funds request of $90,171. We ask that you approve our request to ensure compliance with our Schedule of Special Inspections responsibilities.
